Title: X-ray detector
Inventor: HAYASHI AKIMINE
IPC: G01T1/24
Filed: 1987-02-23
Abstract: PURPOSE:To detect X-rays at a plurality of arbitrary positions by separating electrodes into a plurality of systems, by a method wherein a photoelectric converter means is provided so as to be held between the first and second electrodes and a means for converting X-rays to visible light is provided on the side of either one of the electrodes. CONSTITUTION:This X-ray detector is constituted so that short strip like electrodes 2a-2o and electrodes 4a-4o are formed through a photoelectric converter element 3 composed of a PIN type semiconductive diode so that the projection surfaces thereof cross each other at a right angle and a fluorescent body 5 converting X-rays to visible light is formed on the upper surfaces of the electrodes 4a-4o. When X-rays are allowed to be incident on the upper surface 5a of the fluorescent body 5 at an incident angle right-angled to said upper surface 5a, said X-rays are converted to visible light by the fluorescent body 5 to reach an electrode 2h through an electrode 4h and the element 3. By this mechanism, voltage is generated between the electrodes 4h, 2h and amplified by an amplifier 8 to be indicated by a voltmeter 9. Further, by alternatively changing over changeover switches 6, 7, X-rays can be detected on the arbitrary planar part formed by the projections of the electrodes 4a-4o and electrodes 2a-2o.

Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of noise from a small-sized rotary vibration generator, to change the frequency of the generator, and to reduce the number of parts by constituting the generator so that a permanent magnet itself can be rotated and vibrated when the switch of a circuit which converts the N and S poles of an electromagnet to each other is turned on and the circuit is actuated upon detecting a radio wave or other external information. SOLUTION: A container 3 housing a permanent magnet 4 is provided near the magnetic pole of an electromagnet and a circuit which is automatically turned on and, at the same time, converts the N and S poles of the electromagnet to each other upon catching a radio wave or other external information is incorporated in a vibration generator. When a control signal is inputted to an oscillation circuit, phase-shifted pulse signals are alternately turned on and off at regular time intervals in phases A and B. When the signals are turned on in the phase A, the permanent magnet 4 itself starts to rotate and generates vibrations, because the N and S poles of the magnet 4 are respectively attracted to the S and N poles of the electromagnet.  When the signals are turned on in the phase B, the magnet 4 itself similarly starts to rotate and vibrates in accordance with the eccentricity of the magnet 4, although the magnetic poles of the electromagnet become opposite to the phase A.
